From bbfa7c42337bb619e6af20bf051fe0755ed5a9fd Mon Sep 17 00:00:00 2001 From: Tobias Mueller Date: Tue, 20 Feb 2018 17:34:14 +0100 Subject: python: Fix crash by leaving struct members intact * lang/python/setup.py.in: Copy gpgme.h instead of parsing it. -- The python bindings tried to parse deprecated functions out of gpgme.h. This fails for the current gpgme.h in that it removes an entire field in the key sig struct (_obsolete_class). Hence, the fields were off by an int and the bindings accessed struct members via the wrong offset. That caused python program to crash. At least on 32bit platforms, the crash can be easily triggered by accessing key.uids[0].signatures. On 64bit platforms the compiler probably aligns the struct so that the missing 4 bytes are not noticed. With this change, the python bindings will expose all functions that gpgme exposes, including the deprecated ones. Credits go to Justus Winter for debugging and identying the issue.
